본 고안은 프레스 가공작업시 피가공물의 표면에 오일을 분사시킴에 있어서, 별도의 오일펌푸를 구비하지 않고도 금형자체의 하강작동시 압축공기를 형성하여 이를 오일분사구로 인출하므로서, 메스트로크마다 피가공물에 오일을 분사토록 하는 프레스의 스트로크를 이용한 오일분사장치에 관한 것이다.The present invention, in spraying oil on the surface of the workpiece during press working, forms compressed air during the lowering operation of the mold itself, without drawing a separate oil pump, and draws it into the oil injection hole, thereby processing the workpiece for each stroke. The present invention relates to an oil spray device using a stroke of a press for spraying oil onto the oil.

일반적으로 프레스를 가공시에는 가압용 펀치다이와 피가공물의 마찰로 인한 발열을 억제하기 위하여 그 표면에 오일을 분사도포하므로서 양질의 제품을 얻고 있다.In general, when the press is processed, a high quality product is obtained by spraying oil on the surface of the press die to suppress heat generated by friction of the workpiece.

그런데, 종래의 오일분사 도포장치는 프레스 장치의 일측에 별도의 오일분사펌푸를 설치하여 펀치다이의 하강시마다 오일을 분사해주도록 하고 있는데, 이와 같은 장치는 별도의 오일펌푸를 구비함과 동시, 오일펌푸작동을 위한 별도의 동력을 인출해야 함은 물론이고 오일의 분사간격내지는 시간을 조정하기 위한 별도의 제어장치가 부수적으로 필요하게 되는 관계로, 이들의 설치 및 콘트롤 작업이 복잡하고 난해할 뿐만 아니라, 별도의 많은 설치공간을 요구하게 되면서 전체적인 부피의 증가현상이 발생하고, 제품의 제조원가 상승에 따른 소비자의 부담이 증가되는 등의 문제점이 있었다.By the way, the conventional oil spray coating apparatus is to install a separate oil spray pump on one side of the press device to spray the oil every time the punch die is lowered, such a device is provided with a separate oil pump and at the same time, the oil In addition to drawing a separate power for pump operation, as well as a separate control device for adjusting the time interval of the oil injection interval, as well as their installation and control work is complicated and difficult As a result, a large number of separate installation spaces are required, resulting in an increase in the overall volume and an increase in consumer burden due to an increase in manufacturing cost of the product.

따라서, 본 고안의 목적은 종래의 위와 같은 문제점을 해결하기 위한 것으로서, 상하왕복운동을 하는 상측홀더의 저면일측에는 첵크 밸브장치에 의해 제어되는 유입구를 내설한 피스톤을 설치하였고, 하측홀더상에는 상기피스톤과 형합되어 압축공기를 형성하기 위한 실린더와 그 일측의 펀칭다이 인접부에는 노즐형 분사구를 구비한 오일저장홈을 구비하면서, 실린더 하부 일측으로부터 노즐형 분사구 위치까지는 압축공기 송출을 위한 공기유도관을 부설하므로서, 상측홀더의 항강시마다 피스톤이 실린더내에서 압축동작을 행하여 형성된 압축공기가 공기 유도관을 타고 노즐형 분사구로 분출되므로서, 오일저장홈내의 오일이 분사구를 타고 상승분사되도록 한 것이다.Accordingly, an object of the present invention is to solve the problems as described above, a piston having an inlet controlled by a check valve device is installed on one side of the bottom of the upper holder for up and down reciprocating motion, and the piston on the lower holder. And a cylinder for forming compressed air and an oil storage groove having a nozzle-type injection hole at one side of the punching die on one side thereof, and an air induction pipe for delivering compressed air from one side of the cylinder to the nozzle-type injection hole position. By laying, the compressed air formed by the piston performing a compression operation in the cylinder every time the upper holder descends, is blown out through the air induction pipe to the nozzle type injection port, so that the oil in the oil storage groove is sprayed upward through the injection port.

이를 첨부된 도면을 따라 상세히 설명하면 다음과 같다.This will be described in detail with reference to the accompanying drawings.

도면 제1도는 본 고안의 설치상태도로서, 펀치(11)를 구비하고서 상하 왕복운동하는 상측홀더(1)의 저면일측에 소정길이의 피스톤(2)이 고정부착 설치되는데, 피스톤(2)의 내부에는 외부와 관통되는 공기유입구(21)와 그 하단의 공간부내에는 공기유입구측으로 압축공기가 배출됨을 방지토록 하기 위한 볼(22)이 압축스프링(23)과 체결구(24)로서 지지결합구성된 유입구 개폐 제어용 첵크밸브 수단을 구비하였고, 외주면에는 기밀유지용 링(25)이 삽입설치되어 있다. 이때, 상기 볼(22)은 통상 합성수지로 형성하며, 그 하방에서 지지하는 압축스프링(23)의 탄력은 나사결합된 체결구(24)를 이용하여 실린더 내부와 외부사이에 공기압차가 발생시 볼을 통해 전달된 힘을 받았을때 쉽게 압축될 수 있도록 설정한다.1 is a diagram illustrating an installation of the present invention, in which a piston 2 having a predetermined length is fixedly installed on one side of a bottom surface of an upper holder 1 which includes a punch 11 and reciprocates up and down. The inlet 21 is a ball 22 for preventing the compressed air is discharged to the air inlet side in the space in the lower portion of the air inlet 21 and the lower through the inlet is supported by the compression spring 23 and the fastener 24 A check valve means for opening and closing control was provided, and an airtight ring 25 was inserted in the outer circumferential surface thereof. At this time, the ball 22 is usually formed of a synthetic resin, the elasticity of the compression spring 23 to support the lower side through the ball when the air pressure difference between the inside and the outside of the cylinder using a screwed fastener 24 Set it so that it can be easily compressed when it receives the transmitted force.

또한, 하측홀더(3)의 피스톤(2) 대향위치에는 상기 피스톤의 삽입결합을 위한 실린더(7)가 형성되었으며, 그리고 다이(4) 인접부위에는 노즐형 분사구(6)를 상향 돌출시킨 오일저장홈(5)을 형성하면서, 실린더(7)하단 일측으로부터 상기 노즐형 분사구(6)의 상단 인접부위까지 압축공기 송출용 유도관(8)을 설치하였으며, 분사구와 인접된 유도관의 선단부도 역시 송출되는 공기를 분사구측으로 집중 공급시키기 위하여 노즐형으로 형성하였다.In addition, a cylinder (7) for insertion coupling of the piston is formed at the opposite position of the piston (2) of the lower holder (3), and the oil storage in which the nozzle-type injection hole (6) protrudes upward in the vicinity of the die (4). While forming the groove (5), the induction pipe (8) for delivering compressed air is installed from one side of the lower end of the cylinder (7) to the upper adjacent portion of the nozzle type injection hole (6), and the tip of the induction pipe adjacent to the injection hole is also provided. It formed in the nozzle type in order to concentrate air supply to the injection port side.

이상과 같이 구성된 본 고안의 작용효과를 살펴보면 다음과 같다.Looking at the effect of the present invention configured as described above are as follows.

하측홀더(3)의 다이(4)상에 놓여진 피가공물(9)을 압축성형하기 위하여 상측홀더(1)를 하강시키게 되면, 도면 제2(a)도에서와 같이 피스톤(2)도 공기유입구(21)가 첵크밸브 장치에 의해 차단된 상태에서 동시 하강하면서 실린더(7)내의 공기를 압축하므로서, 압축된 공기는 유도관(8)에 의해 안내되어 노즐형 분사구(6)의 상단으로 분출되는바, 이때 오일 저장홈(5)내에 위치하던 오일이 노즐형 분사구(6)를 타고 상승하여 전방 즉, 피가공물(9)상으로 분사되는 것이다.When the upper holder 1 is lowered to compress the work 9 placed on the die 4 of the lower holder 3, the piston 2 also has an air inlet as shown in FIG. Compressed air is guided by the induction pipe 8 and blown out to the upper end of the nozzle type injection hole 6 by simultaneously compressing the air in the cylinder 7 while simultaneously lowering in the state where the 21 is blocked by the check valve device. At this time, the oil which is located in the oil storage groove 5 is lifted by the nozzle-type injection hole 6 is sprayed forward, that is, on the workpiece (9).

위와 같이 상측홀더(1)는 하강에 의한 프레스 작업을 완료하고 나면 신속하게 원위치로 상승하게 되는데, 이때에는 순간적으로 실린더(7)내의 압력이 대기압보다 낮은 부압이 형성되는바, 실린더 내외부의 기압이 평형을 유지하려는 작용에 의해 대기와 관통되어 있는 유도관이나 공기유입구(21)로 외부공기가 유입되는데, 유도관의 선단부는 노즐형으로 형성되어 공기유입량이 미미하고 주로 공기유입구(21)를 통해 유입된다. 유입된 외부공기는 스프링(23)에 의해 떠받혀져 상기 유입구를 막고있는 볼(22)을 밀어 하강시키게 되므로 실린더(7) 공간 내부로 피스톤의 차기 하강시 압축공급될 공기가 유입되는 것이다. (제2(b)도 참조).As described above, the upper holder (1) is quickly risen to the original position after completing the press work by the lowering, in this case, the pressure in the cylinder (7) is formed at a lower pressure than the atmospheric pressure at the moment, bar pressure inside and outside the cylinder External air flows into the induction pipe or the air inlet 21 penetrating the atmosphere by the action of maintaining the equilibrium. The tip of the induction pipe is formed in a nozzle shape so that the air inflow is insignificant and mainly through the air inlet 21. Inflow. Since the introduced external air is held by the spring 23 and pushes down the ball 22 blocking the inlet, air to be compressed is supplied when the piston descends into the cylinder 7 space. (See also second (b)).

그후 공기유입구(21)를 통해 실린더(7)내에 외부 공기가 충전되어 기압평형이 이루어지면 볼(22)은 압축스프링(23)의 탄력에 의해 상승하여 공기유입구(21)를 막아 공기유출을 방지하는 작용을 행하게 된다.Then, when the outside air is filled in the cylinder 7 through the air inlet 21 to balance the pressure, the ball 22 is lifted by the elasticity of the compression spring 23 to block the air inlet 21 to prevent air leakage. To act.

이와 같이 구성되고 작동되는 본 고안은, 상측홀더(1)의 하강 및 상승동작시마다 피가공물상에 오일의 분사동작과 실린더내에 공기 유입동작이 연속반복적으로 행해지는바, 종래와 같이 별도의 오일분사펌푸 장치와 분사시기 및 시간제어용 제어장치를 배제하므로서, 이들의 별도 설치에 따른 제반비용과 노력 그리고 외부공간 점유면적을 대폭 절감할 수 있고, 제품의 제조원가를 절감하여, 장치의 관리가 간편한등의 특출한 효과가 있는 것이다.The present invention is constructed and operated as described above, the oil injection operation on the workpiece and the air inflow operation in the cylinder are repeatedly performed every time the lowering and raising operation of the upper holder (1), separate oil injection as in the prior art By eliminating the pump device and the control device for injection timing and time, it is possible to drastically reduce the overall cost, effort, and external space occupied by their separate installation, and to reduce the manufacturing cost of the product, making the device easy to manage. There is an exceptional effect.
